Struct CsvDataset 

pub struct CsvDataset { /* private fields */ }

A dataset loaded from a CSV file.

All values are parsed as f64. Non-numeric fields will cause a panic.

Example

// Load iris.csv: 4 feature columns, 1 target column (last)
let ds = CsvDataset::load("data/iris.csv", CsvConfig {
    has_header: true,
    feature_cols: vec![0, 1, 2, 3],
    target_cols: vec![4],
    delimiter: b',',
}).unwrap();

Implementations

pub fn load<P: AsRef<Path>>(path: P, config: CsvConfig) -> Result<Self, String>

Load a CSV file from disk.

pub fn from_string(content: &str, config: CsvConfig) -> Result<Self, String>
